View clinical trials related to Papillomavirus Infections.
Filter by:Human papillomavirus (HPV) infection has become one of the most important health problems faced by women all over the world. A large number of studies have shown that women's cervical, vaginal and perianal precancerous lesions, related cancers, condyloma acuminatum and other sexually transmitted diseases (STD) are closely related to HPV infection. Among them, the persistent infection of high-risk human papillomavirus (HR-HPV) is closely related to the occurrence of invasive cervical cancer. Previous studies have shown that there are significant differences in the effects of multiple HPV infection and persistent infection of different types (such as type-16, -18, -39 and -52) on different levels of cervical lesions, and there is a certain correlation between HPV load in the process of persistent infection and the degree of cervical lesions. In addition, other studies have shown that HPV-16 viral load has certain clinical significance in predicting Cin2 / CIN3 high-grade cervical lesions, and HPV viral load level is significantly different in cervical low-grade squamous intraepithelial lesion (LSIL) and cervical high-grade squamous intraepithelial lesion (HSIL). The above biological changes such as HPV infection type, quantity and proportion can promote the occurrence and development of cervical precancerous lesions and related cancers to varying degrees. It can be seen that the study of the relationship between HPV viral load and cervical lesions is of great significance for clinical disease development prediction and cervical cancer screening.
This phase 3 study will evaluate the immunogenicity and safety of Quadrivalent HPV recombinant vaccine in Chinese females aged 9 to 26 years
The Pocket colposcope has 510k FDA clearance and has been successfully used in almost 1500 unique patients globally in Duke and non-Duke protocols to date. 400 women who are HPV-positive and planned to undergo treatment at 6 Ministry of Health-supported outpatient clinics in Kisumu County will be recruited to the study. After providing informed consent, participants will be randomized 1:1 to either standard-of-care visual inspection or colposcopy with the Pocket Colposcope
A phase 1 random, double blind, positive and placebo control trail was conducted in 120 healthy women in the arm A: 18-26 years old and Arm B: 27-45 years old. The 40 subjects to be inoculated with low, middle, and high dose vaccinefirst in sequence if there was no safety issue. In each dose group SCT1000 : placebo: positive =3:1:1.Two arms can be recruited at the same time. If the DSMB assessment shows that the adverse events of a certain dose group meet the criteria of suspension / termination, the dose group will be suspended / terminated, and the vaccination of this dose group or higher dose group will not be carried out, and the study of other dose groups will continue. If this happens at a low dose, the study will be suspended / terminated.
The study aims to evaluate whether organised, concomitant HPV vaccination and HPV screening offered to all resident women aged 22-27 will result in a more rapid elimination of HPV infection in Sweden. This objective will be examined at the population level.
The DepIST-H study, funded by the French AIDS and Hepatitis Research Agency (ANRS), is to estimate prevalence (the number of cases over a given period of time) and incidence (the number of new cases over a given period of time) of anal lesions (condylomas, dysplasia, cancers) by HIV status among MSM in Lomé, Togo
This phase 3 study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese females aged 9 to 45 years
The purpose of this study to access the relations between genital microecology, HPV infection and cervical intraepithelial neoplasia of childbearing-age female in China
This is a multi-centre, randomised, double blind, placebo-controlled study on female participants with diagnosis of high-risk human papillomavirus (HR-HPV) infection to evaluate the clearance capacity of AHCC®.
This project aims is to monitor the effectiveness of HPV vaccination in real-word conditions, at least 7 years after initiation of HPV vaccination in Sikkim. This study would give an opportunity to provide rapid feedback to the Indian public health authorities about the impact of the HPV vaccine.
